Deep space avionics resets in VAB after simulation if Basic Avionics is queued for research

Found an interesting issue when the first deep space avionics (basic avionics) is queued for research but not researched yet:
set an avionics to deep space
save the vessel
reload the vessel
the avionics has changed to near-earth instead of deep-space
Clearing the vessel and reopening it, simming and returning to VAB or leaving the VAB entirely and then reloading it will all do this.

I don't see any sign an issue was raised here. I experienced the same bug in release v17.21.0.0. I've included a game save and a craft to hopefully save time while debugging. My extra mods are quality-of-life and not parts mods. CKAN mod list included in the archive.
